The first step in water quality analysis is collection of samples that accurately represent the quality of the water being sampled. In order for an analysis of a sample to be accurate, the characteristics of the water sample must remain unchanged. Proper sample preservation, transportation, and storage are discussed. This article is an excerpt from the AWWA publication Water Quality Analyses.
